Abstract:
Plasma CO2 splitting to CO over oxygen-deficient Mo-doped CeO2 under mild conditions was investigated for the first time, showing ∼20 times higher CO2 conversion compared to pure CeO2, which can be attributed to the increased oxygen vacancies (VO) and the formation of Ce3+-VO-Mo on the catalyst surface. Importantly, VO sites showed excellent catalytic stability.
